For the past few years, we've watched their relationship, which started on The Hills, implode time and time again. While we thought the pair finally mended their fences (Heidi congratulated LC on her wedding to William Tell onTwitter), it turns out this is NOT the case.

On a recent episode of Marriage Boot Camp, Montag revealed her resentment and anger towards her former friend. Spencer Pratt's wife apparently still holds a grudge for the poor treatment she received at the hands of Conrad during theirMTV days.

Luckily for us LB fans, it turns out the One Tree Hill star DID attend his 10 year high school reunion over the weekend, and while he was there, he took some fun photos with Lauren and her new hubby, William Tell!

Aww, we're glad everyone got along!

In the photo booth snaps, the trio dons some silly accessories as they ham it up and strike some adorable poses for the camera.
